Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a detachable ground dust collecting device for an underground silo. Background Art

[0002] In most of my country's steel industry underground silos, a large amount of dust is generated during the process of borrowing and transporting raw materials by belt conveyors. Generally, dust collectors are equipped with fixed dust hoods to remove dust and clean the underground silos. However, in the actual dust removal process, part of the dust in the underground silo is in the dead corner of the fixed dust hood and cannot be sucked away by the fixed dust hood. This part of the dust will fall to the ground of the underground silo, affecting the working environment of the silo.

[0003] At present, in response to this technical problem, some companies have proposed adding a movable dust collector to remove dust and clean the ground of the underground silo. The existing patent CN 208905594 U discloses a floor dust suction device for a production workshop, which includes a dust suction fan with a motor, and the dust suction fan is fixed on a carrier vehicle. A dust removal box and a filter box are also fixed on the carrier vehicle. The dust removal box and the filter box are connected by a connecting pipe, and the dust removal box is connected to the suction nozzle through a dust suction hose. A backflush box is provided above the filter box, and the backflush box is connected to the dust suction fan. A filter screen is provided at the connection between the filter box and the backflush box, and a backflush cleaning device is provided on the backflush box. When the device is used for collecting dust on the ground of an underground silo, since the device is installed as a whole on a carrier, the carrier and the device on it need to be hoisted as a whole to the ground of the underground silo, which increases costs; when workers perform dust removal operations, they need to push the carrier to remove dust, which involves certain operating difficulties; since the overall weight of the carrier and the device is relatively large, it is difficult for workers to push them, and the labor intensity is high; and the overall space occupied by the device is relatively large, and it is inconvenient to repair and operate the overall device within the limited space of the underground silo. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a detachable underground silo ground dust collecting device to achieve the purposes of convenient operation, convenient maintenance, large operating range and low labor intensity for workers.

[0005] To achieve this technical purpose, the utility model adopts the following scheme:

[0006] A detachable ground dust collecting device for an underground silo comprises a dust collecting fan with an electric motor, a filter box, a dust removal box and a dust collecting nozzle, the dust collecting fan is connected to the filter box, the filter box is connected to the dust removal box, the dust removal box is connected to the dust collecting nozzle, the dust collecting fan, the filter box and the dust removal box are respectively installed on the ground, the dust collecting nozzle is placed on the ground of the underground silo, and the dust collecting nozzle is connected to the dust collecting nozzle through a dust collecting pipe; the dust collecting pipe comprises a dust collecting main pipe and a plurality of dust collecting branch pipes respectively connected to the dust collecting main pipe, and the dust collecting branch pipes are connected to the dust collecting nozzle through a dust collecting hose.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] The utility model installs the dust collecting fan, filter box and dust removal box above the ground without lifting. When workers are cleaning the ground of the underground silo, they do not need to push the entire equipment but only need to push the dust collecting nozzle, which effectively solves the problem that the overall space occupied by the device is large and the movement is inconvenient, reduces the operating difficulty and labor intensity, and facilitates subsequent device maintenance. The dust collecting pipe is arranged in the form of a plurality of dust collecting branch pipes, which can expand the dust collecting operation surface and improve the dust collecting efficiency.

DETAILED DESCRIPTION

[0019] In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific implementation methods, but the present invention is not limited thereto.

[0020] A detachable underground silo ground dust collection device, such as Figure 1 As shown, it is mainly composed of a dust collecting fan 2 with a motor 1, a filter box 3, a dust removal box 4 and a dust collecting nozzle 8. The dust collecting fan 2, the filter box 3 and the dust removal box 4 are respectively fixedly installed on the ground, and the dust collecting nozzle 8 is placed on the ground of the underground silo; when specifically connected, the dust collecting fan 2 is connected to the filter box 3, the filter box 3 is connected to the dust removal box 4, and the dust removal box 4 is connected to the dust collection nozzle 8 through the dust collecting pipe 5.

[0021] like Figure 2 , Figure 3 As shown, the dust collecting pipe 5 is composed of a dust collecting main pipe 501 and 3-6 dust collecting branch pipes 502. The dust collecting main pipe 501 is an inverted L-shaped structure as a whole. The lower end of the dust collecting main pipe 501 is connected to the dust collecting branch pipes 502 through a multi-channel joint. In this embodiment, four dust collecting branch pipes 502 are provided, and each dust collecting branch pipe 502 is respectively installed with a valve 6, and the valve 6 is used to control the on-off status of the dust collecting branch pipe 502.

[0022] The dust collecting branch pipe 502 is connected to the dust collecting nozzle 8 via a dust collecting hose 7, and the dust collecting hose 7 in this embodiment is a telescopic hose.

[0023] Traveling wheels 9 are respectively installed at the bottom of both sides of the cover body of the dust collecting suction nozzle 8, and the dust collecting suction nozzle 8 rolls on the ground of the underground silo through the traveling wheels 9.

[0024] In this embodiment, an armrest 10 is further provided on the upper portion of the dust collecting nozzle 7, and the armrest 10 is used to push the dust collecting nozzle 8 to move.

[0025] When the device is used, the number of dust collecting nozzles 8 is determined according to the working surface to be dusted, and then the dust collecting nozzles 8 are respectively connected to the dust collecting branch pipes 502 through the dust collecting hoses 7. For the dust collecting branch pipes 502 that are not connected with the dust collecting nozzles 8, a plugging head 11 is added to the end to seal them to protect the dust collecting branch pipe openings and prevent them from rusting or being blocked by debris; then the valve 6 of the dust collecting branch pipe 502 installed with the dust collecting nozzles 8 is opened, and the motor 1 of the dust collecting fan 2 is started to make the dust collecting fan 2 Negative pressure is generated inside the device, and the handrail 10 on the dust collecting nozzle 8 is held and moved to clean the dust and other debris on the ground of the underground silo; the dust and other debris on the ground of the underground silo pass through the dust collecting nozzle 8, the dust collecting hose 7, the dust collecting branch pipe 502 and the dust collecting main pipe 501 into the dust removal box 4, and the solid particles with heavy specific gravity are filtered out inside the dust removal box 4, and then the debris with light specific gravity enters the filter box 3 for further filtration, and finally is discharged by the dust collecting fan 2 to form relatively clean air.

[0026] The device installs the dust collecting fan, filter box and dust removal box above the ground. When cleaning the ground of the underground silo, it is only necessary to connect the dust collecting nozzle to the dust collecting pipe, and there is no need to hoist the entire device to the ground of the underground silo. When cleaning, the worker only needs to push the dust collecting nozzle to move, without pushing the entire device, which solves the problem that the device as a whole occupies a large space and is inconvenient to move when placed on the ground of the underground silo, reduces the difficulty of operation and labor intensity, and is not limited by the working space on the ground of the underground silo, which facilitates the maintenance of subsequent devices. The dust collecting pipe is arranged in the form of several dust collecting branch pipes, and multiple dust collecting nozzles operate at the same time, which expands the dust collecting working surface and improves the dust collecting efficiency.

[0027] Finally, it should be noted that the above-listed examples are only preferred embodiments of the present invention. Of course, those skilled in the art can make changes and modifications to the present invention. If these modifications and modifications fall within the scope of the claims of the present invention and their equivalent technologies, they should be considered to be within the scope of protection of the present invention.
